EVO 2014, an insight view with Ralf Grösel
Ralf, to start simple, what´s new about the 2014 EVO?
Ralf Grösel: A lot!! The Evo 2014 is not based on the 2013 model but a completely new design coming out of two different prototype directions. This Evo is a kite I´ve been developing for the last two years, this means the first prototypes have already been built parallel to the Evo 2013. Which was kind of strange but necessary to come from a new approach.
What was the challenge about it and why did the development take so long?
Ralf Grösel: Since the introduction to the market in 2008 the Evo was very Delta-oriented. This concept direction offers a lot of positive aspects, but also a lot of limiting factors. Over the years I really pushed the kites’ overall performance to the absolute limit in-between the concept, until I really came to the point where I just could not improve the Delta-shape anymore in 2013. I already saw that coming in 2012 and therefore needed the time to work in time on the new concept and be ready after these two years for a new direction.
What do we have in our hands now?
Ralf Grösel: At the end of the day, a completely new kite, which offers some of the typical Evo genes, but also is a completely different construction and direction. The Evo is trimmed to maximum performance combined with perfect handling. Developed to fit perfectly to a 4 line bar, I found a perfect match for the geometry combining stability with flexibility of the whole kite construction. Not to mention several prototypes…
Sounds a bit like a conflict…
Ralf Grösel: On the first view, yes. But I can explain it easily:
The higher aspect ratio and the flatter radius, which are even similar to a Rebel, have been optimized on the other hand to a very very stiff and compact system through several small changes. A lot of flexibility in the tip area to achieve that great handling, stiffness in the profile for bomb proof stability. But it is indeed tricky to combine these two characteristics, which pull in opposite directions!
Any other changes?
Ralf Grösel: Several, just to mention the changed panel layout, remarkable thinner struts to reduce weight, a different tip geometry and a new bridle system with to rolls at both sides to depower efficiently.
Where in the North Kiteboarding Range is the Evo seen in your view?
Ralf Grösel: The Evo is and will stay the all-round talent inbetween the North Kiteboarding range. But, the Evo made a huge step forward regarding the overall performance. Steady is the extremely easy water relaunch and the brilliant stability.
What does that mean in detail for the pilot?
Ralf Grösel: The general speed of the kite in the wind window has increased, the upwind ability is just insane and the depower is now massive. Jumping is super easy, anybody can boost highest jumps with smooth landings with this kite. Compared to last years models flight time and height has increased a lot.
NKB: Where is the Evo´s position next to the completely new Dice?
Ralf Grösel: The Dice is nothing more or less then the jackpot. We never had a kite which started this fast and with so many good feedback from team riders and customers at the same time, never sold several thousand pieces of one kite model in the first year.
Still, the Evo is a different concept with 5 struts and all the benefits which come with it and the potential to surprise, especially Evo lovers! The Dice is a specialist´s kite for advanced freestyle/wakestyle and advanced wave riding. The Evo´s jumping ability for classic moves and classic riding are just easier and more stable. As mentioned, the Evo jumps high, wide and long!
Test one, you´ll be surprised!!
Thank you Ralf for this inside you of your perspective!
Vegas DevelopmentBy Ralf Grösel
The testing and fine-tuning started with the small sizes, from 6 to 10m. Even with just those sizes we made some major changes, I’d even go so far as to say a small Revolution! The 6, 7, 8 and 9m sizes are the best kite designs I have ever built so far. The very first prototypes for this design were already being tested in South Africa back in 2011!! They had been based on the 2011 model but with a different panel layout and alternative profiles. At the end of the development of the Vegas 2012, I knew this system had been developed to its limits – time for a change. So I started to invent a new Vegas platform parallel to the existing shapes, not wanting to mess anything up, the Vegas is such a great kite, but I was looking for that extra element. As it often happens in life, after many prototypes and designs on the computer, the final piece of the puzzle came from a direction I first didn’t think of, it happened during the final phase of the Neo 2012 development. This means, the Vegas 2013 is based more on the Neo design than on the last Vegas design! It might sound strange and may lead to you thinking the Neo was developed for three struts, which it definitely wasn’t at all. The reason is all the new elementary knowledge about steering-input, the stiffness of structures and new Tip-Layouts of three strut kites! But don’t you worry, the Vegas is still a pure Vegas. Just the new results made me rethink some common physics in kite design and made me able to design the best Vegas ever. I’d even say, the best high depower C-kite ever…
CHANGES FROM 2012
-More profile in between centre and quarter strut.
-Bigger profile creating bigger pop.
-No tip battens.
-Open radius, even more Cshape.
-Edges in the tips.
-Closing Trailing Edge diameter for more pop and hangtime.
-Changed front pigtails for more variety between Freestyle and Wakestyle.
What’s the result, how does it fly?
-Harmonic, light and very sensitive, progressive increasing sheeting forces.
-Soft steering forces with the best bar feedback in the North Kiteboarding range.
-Massive depower on a short depower stroke.
-Easy hooked in performance with incredible jumping abilities.
-Fantastic control during kiteloops.
-Significantly more pop during unhooked moves.
-Much longer power delay moment during unhooked moves (the moment during the move when the kite is nearly pressure less and gives time to complete complex moves).
-Plenty of pop, even during light winds.
-Catches the rider quickly and easily after radical kiteloops.
-Kites under 10m should always been flown with longest 22m lines.
-Wakestylers should use the inner setting of the bar connection.
-The kite remains much more predictable during the hardest tricks.
-The power delay is recognizable, but not felt as slow, but predictable and constant.
The Vegas never had any performance problems. So what does it take to make it better? It ’s thebalance between the ultimate bar feedback and using that to get the best performance out of the kite. The Vegas 2013 communicates in a very special way with the rider, which has never been there before. Even riders used to other brands recognize in the first few moments the potential and fun the Vegas has to offer. Even without being the best rider on the planet.
